JAMES G. ARNOLD, OF WORCESTER, MASSACHUSETTS.

LETTER- Speccaton of Letters Patent No To all whom t may concern.

Be it known that I, JAMES G. ARNOLD, of the city and county of 1Worcester and State of Massachusetts, have invented certain new and useful lmprovements in Letter-Envelops; and I hereby declare the following to be a full, clear, and exact description of the same, due reference being had to the accompanying drawings, in which- Figure l shows the envelop and Fig. 2 the paper before folding.

The objects of my invention are to produce letter envelops by a more economical use of the paper than any of the forms or patterns now in use and to make the back smooth or as free from folds as possible, to accommodate printing thereon and still to make a neat or in other words, a marketable envelop; and to these ends the nature of my invention consists first in so shaping the pattern that when one piece is cut from the roll or continuous sheet the end of the sheet. is left in the right form to use, and secondly in making the adhering parts that close the ends or sides, to consist of narrow folds or laps that shall come inside or between the face and back.

To enable others to use my invention I proceed to describe how to make an envelop.

Take a strip of paper a little wider than it is wished'to have the envelop long when inished and cutting it or separating it the right size by a cut that shall make bot-h parts the right form to use, as by the line A, B, C, Fig. 2 the end 0 having been left in formby a former cnt, then folding the sides A, E, and O, Gr, leaving the paper the ENVELOP.

l width desired for the length of the envelop as l, N, Fig. 'l making narrow folds, and then folding the back P at the line D, F, bringing the first folds inside, the adhesive material being applied to the first folded. parts it only remains to fold the lap R at E, G, and the envelop is made as shown in Fig. l. Thus it will be seen that all the paper is used or in other words the pattern cuts without waste and the narrow folds at smooth and in good condition for printing on.

It is evident that some variations from the above will be necessary in making the dierent sizes and styles of envelops; but they being governed by the above principles of construction and producing the same results will suggest themselves in each case; therefore do not wish to be understood as limiting myself to the precise forms or proportions of parts shown; as I do not claim these; but- Vihat l claim as a new article of mannfactnre, is

1. Making letter envelops by cuttinO, folding and pasting the paper substantially in the manner and for the purposes, above set forth and described.

2. Folding narrow folds at the ends or sides so as to come inside between the face and back in the manner and for the purposes susbstantally as above set forth and described.
